tabs said:The boiler was a worcester 37kw cdi - done it now , nice easy straightforward job.
Don't why the rating of the boiler should affect your price in the US though?
I guess a car with 200 horse power and one having 460 HP is the same price mate ONE Boiler fits all applications ..
Put it this way if the boiler is 1,000,000 BTU in put you need 3 blokes to install it IF the boiler is 30,000 BTU in put I hire a 9 year old child to carry it in and set it in place
I would also imagine EVEN in your country that the larger the boiler in put the more gas volume needed or larger electrical power supply
See the education you just received
I don't know about the education I just received off you but over here there ain't much difference in labour costs on installing anything from a 20kW to 42kW combi- we were talking domestic boilers - we do not install comercial sized boilers in domestic houses ! Something to do with not wasting energy i think
